About PSA, Total (2.5 ng/mL cutoff)

PSA, Total (2.5 ng/mL cutoff) is a blood-based laboratory test from Quest Diagnostics that measures total prostate-specific antigen levels in serum, using a lower 2.5 ng/mL threshold to support earlier detection of potential changes in prostate health. This test is designed for men seeking proactive monitoring of PSA levels as part of routine health screening.

Why It's Worth Considering: The 2.5 ng/mL cutoff — lower than the traditional 4.0 ng/mL threshold — reflects a more conservative reference range, making it a useful option for men under 60 or those with a family history who want earlier insight into PSA trends over time.
